Harbaugh went on a curious tangent this week when talking about a small wager with linebacker Za'Darius Smith.

"I had a bet with him last week -- maybe that’s against the rules to have a bet with a guy -- but it was only a dollar, so I have to read the CBA and see what the rule is on that," Harbaugh said, drawing laughter from reporters.

This week marked the Ravens' first offseason practices since the NFL forced the team to cancel three organized team activities for putting rookies and first-year players in pads. The Ravens were fined $343,057 and Harbaugh was docked $137,223.

Harbaugh explained the violation was the result of his misinterpreting some amendments to the collective bargaining agreement. On Tuesday, he touched on the topic of modified language in the CBA when addressing whether Smith was in the neutral zone early at a recent practice.

"[We] went back and watched the tape frame-by-frame, and he was not in the neutral zone," Harbaugh said. "He was right on time, and actually, one of the linemen had even flinched. I have to pay him a dollar, but I’m going to wait until I check my side letter on that.”

The guess here is Harbaugh won't be too upset about losing a $1 bet. It was probably worth it to give that subtle jab to the league and the CBA.
